Objective To investigate the clinical features, etiology and prognosis of children patients with unexplained liver dysfunction. Methods The clinical data of 205 inpatients with unexplained liver dysfunction from January 2016 to December 2017 were analyzed retrospectively. The clinical characteristics, etiology and prognosis were analyzed. Results Of 205 patients with unexplained abnormal liver function, 166 patients with liver dysfunction (80.97%) were clearly diagnosed and involved in a variety of diseases. Among them, 104 cases were infected liver damage caused by non-hepatophilic virus, 38 cases were related to genetic metabolic diseases, 11 cases were drug-induced liver damage, 6 cases were Kawasaki disease, 4 cases were hematologic tumor diseases, 3 cases were malnutrition. The cause of abnormal liver function was not clear in 39 cases. Conclusion There are many and complicated causes of abnormal liver function, and part of the causes are unknown. Infantile liver dysfunction was mainly caused by non-hepatophilic virus, the first was cytomegalovirus, the second was Epstein-Barr virus; genetic metabolic disease, drug-induced liver damage, systemic disease are also an important cause of liver dysfunction.

目的 对比观察单孔、单操作孔及三孔胸腔镜治疗早期非小细胞肺癌(NSCLC)的临床疗效。方法 选择125 例早期NSCLC患者,分为单孔组(38例)单操作孔组(42例)和三孔胸腔镜组(45例),观察3组手术结果和并发症发生率。结果 3组患者均顺利完成手术,无中转开胸。单孔组手术时间长于单操作孔及三孔组,差异有统计学意义(P＜0. 05)。对比所有3组手术患者的术中出血量及淋巴结清扫数目、术后总引流量及引流管留置时间、术后并发症发生率,差异无统计学意义(P＞0. 05)。单孔组及单操作孔组术后疼痛程度评分优于三孔组,差异有统计学意义(P＜0. 05)。结论 单孔及操作孔胸腔镜治疗早期NSCLC已可取代三孔胸腔镜技术,其术后恢复快,疗效确切,其中单孔手术对设备及胸腔镜医师操作技术熟练程度等要求更高,故在设备仍未有突破性的进展时,单操作孔胸腔镜手术可作为治疗早期NSCLC的优先选择。

Objective To compare the clinical effects of uniportal video-assisted thoracic surgery (VATS), single utility port VATS and 3-portal VATS lobectomy for patients with early stage non-small cell lung cancer. Methods Patients were divided into uniportal VATS lobectomy group(n=38), single utility port VATS lobectomy group(n=42) and 3-portal VATS lobectomy group (n=45). The surgical results and complication rates were observed. Results All patients completed the operation successfully, no one was changed to open operation. Operation time in uniportal VATS lobectomy group were longer than single utility port VATS lobectomy group and 3-portal VATS lobectomy group(P＜0. 05). There were no significant differences in intraoperative blood loss, number of lymph node dissection, the amount and time of postoperative extubation, and the incidence of postoperative complications(P＞0. 05). Post-operative pain score were higher in 3-portal VATS lobectomy group than in uniportal VATS lobectomy group and single utility port VATS lobectomy group (P＜0. 05). Conclusion Uniportal VATS lobectomy and single utility port VATS lobectomy can replace the 3-portal VATS lobectomy in treatment of early NSCLC, because of the faster postoperative recovery and curative effect. Uniportal VATS lobectomy requires special equipment and more operation skills, as there is no breakthrough in the equipment, single utility port VATS lobectomy may still be used as the first choice for treatment of early NSCLC.

Objective It was evaluated the clinical effect of the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with Breviscapine combined with self-blood acupoint injection therapy. Methods Routine treatment methods were used in the controlled group. Breviscapine and the self-blood acupoint injection therapy were added into the treatment group. St George's respiratory questionnaire (SGRQ) and chronic obstructive pulmonary disease assessment test (CAT) were done in all enrolled patients. And the total score of SGRQ, the score of CAT and the length of stay in hospital were assessed. Results There were positive relationships between the total score of SGRQ, the score of CAT and the length of stay in hospital.compared with the controlled group, before and after the treatment, significant difference was not observed with the overall score of SGRQ in the treatment group, but was observed with the score of CAT in the treatment group, and stay time in hospital in the treatment group was declined obviously. Conclusion The total score of SGRQ and the score of CAT could reflect the conditions of AECOPD, and the latter was more suitable for the evaluation of the condition change in short period. The clinical effects were obvious in the treatment of AECOPD with Breviscapine combined with self-blood acupoint injection therapy.

目的 探讨纵隔髓外造血(EMH)的临床特点,从而为其诊断、治疗提供参考意见。方法 总结分析我科收治的1例双侧后纵隔骨髓外造血组织多发瘤样增生,并对近10年来国内相关文献报道的27例病例进行回顾性分析。结果 患者需行手术活检取得病理诊断,确诊髓外造血。结论 纵隔髓外造血瘤样增生是一种罕见特殊的良性病变, 预后良好。但因其临床表现和影像学均缺乏特异性,当临床中遇到发生在后纵隔脊柱旁的占位性病变,同时患有贫血的患者应考虑EMH 的可能性,给予经皮穿刺或者胸腔镜下活检来取得细胞学诊断,从而避免不必要的手术治疗。

Objective To probe into the clinical features of mediastinal extramedullary hematopoiesis (EMH), for providing a reference for clinical diagnosis and treatment. Methods The clinical data was studied in a case of mediastinal EMH from our department, and 27 case reports from domestic published literatures over the last decade were analyzed retrospectively. Results Of the 27 patients, 15 received surgical excision, while the other 12 underwent needle biopsy. In our patient, the diagnosis of EMH was made by mini thoracotomy and open biopsy. Conclusion Mediastinal EMH is a rare disease and its prognosis is well. Because there is no obvious specific clinical symptoms and imaging appearances, the possibility of EMH should be considered when a patient with a mediastinal tumor associated with anemia is encountered. Diagnosis can be achieved by needle biopsy or video-assisted thoracic surgery (VATS) in order to prevent unnecessary surgical procedures.

Objective To construct the eukaryotic expression vector of the cancer suppressor gene, SEMA3B, and research the effects on malignant biological behavior of lung cancer A549 cells. Methods By reverse transcriptase-polymerase chain reaction (RT-PCR), the full length SEMA3B gene was amplified and then was inserted into pcDNA3.1. The recombinant plasmid pcDNA3.1-SEMA3B was confirmed correctly through double enzyme digestion and PCR identification, which was transfected into lung cancer A549 cells by lipid media transfection. The untransfected A549 and A549 transfected with pcDNA3.1 were used as controls. SMEA3B gene was detected by qRT-PCR and western blot. MTS assay, flow cytometry, and colony formation test were performed to evaluate the effect of overexpression of SEMA3B gene on A549 cell proliferation, apoptosis, cell cycle, and colony forming ability. Results The amplied fragment of SEMA3B gene by PCR was consistent with the anticipated result, the SEMA3B gene was cloned successfully. And the recombinant plasmid pcDNA3.1-SMEA3B was constructed successfully through gene sequence identification. After transfection of pcDNA3.1-SEMA3B, SEMA3B mRNA and protein expression levels were raised, and overexpression of SEMA3B gene in A549 cells significantly inhibited the proliferation of A549 cells, induced apoptotic cell death, blocked cell cycle in the G1 phase, and suppressed cell colony-forming ability. Conclusion The recombinant pcDNA3.1-SEMA3B is constructed successfully. SEMA3B gene can significantly inhibit the malignant biological behavior of lung cancer A549 cells.
